The Quantech Myoglobin Assay is intended to be used as an aid in diagnosing myocardial infarction in patients exhibiting chest pain. It is intended to be used in conjunction with EKG, and physician examination, as well as possibly other biochemical blood tests to rule in or out non-cardiac damaging origin of the chest pain.

The Quantech Myoglobin Assay is based on the principle of two site, or sandwich immunoassay in combination with SPR surface mass measurement. Each test module contains a solid phase anti-myoglobin monoclonal antibody immobilized onto a gold surface. An anti-myoglobin enzyme conjugate solution and wash solution are used to enhance the specific detection of myoglobin. The Quantech assay utilizes myoglobin-specific antibody to capture the myoglobin in the sample. This is followed by a quantitation of the surface mass increase using surface plasmon resonance (SPR), to measure the myoglobin in serum.
